You need to install one. See

Even though I have Java in the system, it seems Eclipse just won't launch or associate with it, not sure how to config it so that it does

I assume you have a 64 bit machine, since you said (in a related thread)
you have a 64 bit Java VM? Once you've confirmed that, you'll want to be
sure you got the 64 bit version of Eclipse. (The 32 bit version will run
on a 64 bit machine, but only if you have a 32 bit VM).

In the worst case ... if the eclipse.exe can not find your vm for some
reason, or if you have multiple ones and you want to pick which one is
used, you can use the "-vm" argument to specify the path to your java vm.

See
http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse. platform.doc.user/tasks/running_eclipse.htm


You might also be interested in the eclipse.newcomer newsgroup/forum.
That's where questions like this would normally be asked/answered and
some there might have more insight or advice about "getting started".

Good luck,

If you downloaded a 64-bt Eclipse bundle, you have to install a 64-bit
version of the JRE. Since AFAIK the Java 5 64 bit JRE bundles do not
register as "public" JREs, Eclipse might not find any suitable 64-bit
JRE. In this case, try one of the following:

1) run eclipse with the -vm <path> command parameter, pointing to your
64-bit JRE (ex.: 'eclipse -vm "c:\Program Files\jre1.5.0_etc"')
2) edit eclipse.ini in Eclipse installation directory and add the -vm
parameter above, then run eclipse normally

(if you're using Eclipse 3.6)

HTH.
Mauro.

I had the same exact problem with Win7+Eclipse3.6+JRE1.6 and it said it couldn't find java. The solution was to add the location of JRE to my path variable. To do this on Win7 follow the instructions below (may be similar for other Windows versions):

Right-click "My Computer", select "Advanced system settings" on the left, Click on the "Environment Variables..." button in the System Properties dialog.

In the Environment Variables dialog scroll through the System variables and click on the "Path" variable, click the "Edit..." button.

In the Edit System Variable dialog click in the Variable value text box, scroll to the end of it, and then add a semi-colon ";" (to separate different paths) and then add the path to the JRE, in my case it was "C:\Program Files\Java\jre6\bin" which is the default location. Click the "OK" button, "OK" again, and "OK" one last time.

Try running Eclipse now. That's all I had to do. Hope this helps others out there.

You should instead associate a JDK (not a mere JRE) with Eclipse via the
-vm option in eclipse.ini as the earlier respondent said. (I say this so
that subsequent readers of the thread may know the correct way of doing
this.)
